OP, Gypsy Vanners, not Gypsy crosses, are generally a small breed. Yes, they come in black and white. I think Bubba was confusding you with all of her pictures. If the horse you saw was small with quite a bit of feathering and a thick mane and tail, there is a good chance it could be a Gypsy Vanner, but could also possibly be a draft cross of some sort that could be contributing to the size. Crosses don't usually have an enormous amount of feathers or extraordinarily thick manes and tails though, but I guess it could happen.
